Advanced technology: Traditional spine surgery for the naked eye operation, the field lighting and vision, etc., had to expand the incision, expand the exposure to ensure the safety of surgery, resulting in increased surgical trauma, slow postoperative recovery, increased complications, now developed countries have basically abandoned the traditional naked eye spine surgery operation. Microscope-assisted direct vision spine surgery, which began in the 1970s, is a perfect combination of traditional spine surgery techniques and microsurgery techniques, which has the advantages of small incision, less trauma, less bleeding and faster postoperative recovery and wide indications, and ensures the accuracy and safety required for spine surgery. It is suitable for all types of lumbar disc herniation. We also use general anesthesia with tracheal intubation, prone position, precise positioning under X-ray fluoroscopy, and then make small incisions to routinely reveal the surgical area, and place a German Leica microscope to complete the technical operations such as spinal canal decompression, nerve root decompression, intervertebral discectomy and intramedullary tumor removal under the microscope, which ensures clear vision and 4 times magnification. This procedure can be said to have no significant drawbacks due to the clear vision and 4 times magnification, which ensures the absolute safety of surgical operation and greatly improves the accuracy. Indications: (1) lumbar disc herniation of the types used; (2) anterior and posterior surgery for cervical spondylosis (3) thoracic and lumbar spinal stenosis; (4) intramedullary and extramedullary lesions such as intra-vertebral canal tumors. During my study in the United States, I received training in microscopic techniques. At present, only I carry out this technique in our department, with dozens of cases and patients aged 87 – 26 years old, with 100% patient success rate and 100% excellent rate. We especially remind those young patients who do not want to undergo fusion surgery that this can be the best choice for their first surgery! General anesthesia, the patient has no fear of surgery. Pre-operative initial body surface positioning, precise positioning is needed before cutting The whole procedure is done under a microscope to ensure patient safety and surgical precision Complete removal of the large nucleus pulposus tissue to ensure more complete decompression The incision length is less than 3.5cm, with intracutaneous sutures, aesthetically pleasing, and no need to remove stitches.
